Filed: 1992-11-26
Abstract: TRANSMISSION CONTROL SYSTEM WITH LOAD     COMPENSATED SHIFT MODULATION  Abstract of the Disclosure A vehicle has a powershift transmission driven by an engine via a torque converter.  The transmission is shifted by pressure operated clutches which are controlled by electrohydraulic pressure control valves.  A speed ratio value representing a ratio of the torque converter output shaft speed to the torque converter input shaft speed is determined. A minimum clutch pressure value and a slope value are determined as a function of the speed ratio value.  During a shifting of the transmission, a pulse-width-modulated signal applied to the valve is controlled so that the pressure applied to the clutch will vary from the minimum clutch pressure to a maximum clutch pressure at a rate proportional to the slope value.

Inventor: ZOUMALAN SARKISS
IPC: G01N30/18
Filed: 1993-01-19
Abstract: ABSTRACT A method for determining the concentration of a tracer, e.g. nitrogen-bearing marker dye, in a hydrocarbon liquid, e.g. gasoline.   In the present method, a sample of the marked hydrocarbon liquid which is to be analyzied is prepared by adding a known volume of a nitrogen-bearing, "internal standard" thereto.  The sample is then heated, preferably in a gas chromatograph, to vaporize, separate, and measure the dye and the internal standard.  These measurements provide a ratio which is matched or compared to a predetermined, reference ratio which, in turn, is representative of a known concentration of the dye in the sampled hydrocarbon.

Abstract: An improved ceramic heater to be incorporated in a glow plug is described.   The heater is made up of a ceramic core enclosed by 2 ceramic layers sintered together to form a unitary ceramic heater.   All  three component elements of the heater are composed of silicon nitride containing different concentrations of an electrically conductive ceramic substance, such as titanium nitride, titanium carbonitride or molybdenum disilicide.   Each component additionally contains low amounts of sintering additives.  The core of the heater, is a ceramic rod which has  the  highest  concentration  of  the  electrically conductive substance.  The core is enclosed in a ceramic layer which is an electrical insulator and is composed of silicon nitride, less than 28 vol.% of the electrically conductive ceramic substance and sintering additives.  The second layer over the core contains the electrically conductive ceramic substance in a concentration which is in between that in the core and that in the insulator layer.  One end of the rod is integrally connected to the second layer over it.  The ceramic heater is fitted into a glow plug housing.   The core and the second layer properly joined to appropriate connectors in the glow plug housing form an electrical circuit when connected to an electrical power source.

Abstract: The voice over data component of a personal communications system enables the operator to simultaneously transmit voice and data communication to a remote site.  This voice over data function dynamically allocates data bandwidth over the telephone line depending on the demands of the voice grade digitized signal.  The user may enter voice over data mode from a data transfer mode by lifting the handset of the telephone connected to the modem.  The off-hook condition is sensed and software sends a supervisory packet to the remote site to invoke voice-over-data mode.  The remote telephone will simulate a ring to alert the remote user, and the local telephone will simulate a ringback to inform the caller that the remote unit is responding.
